CARPET-STRETCHER.

To all whom it may concern:

Be it known that I, ANDREW F. ll IoBn'rrI, a citizen of the UnitedStates, residing at VVaitsburg, in the county of lVallawalla, State ofWashington, have invented certain new and useful Improvements in Carpet-Stretchers; and I do hereby declare the following to be a full, clear,and exact descrip tion of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to carpet stretchers.

One object of the invention is to provide a novel head block for carpetstretchers.

A second object of the invention is to improve the general constructionof devices of this character.

Vith the above and other objects in view the invention consists ingeneral of certain novel details of construction and arrangements ofparts hereinafter fully described, illustrated in the accompanyingdrawings, and specifically set forth in the claims.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and :Figure 1 is a perspective View of acarpet stretcher constructed in accordance with this invention. Fig. 2is a section on the line 22 of Fig. 1. Fig. 3 is a section on the line33 of Fig. 1. Fig. 4 is a section on the line 14 of Fig. 1.

This carpet stretcher is provided with a head block 10 consisting of anupper plate 15 and a lower plate 14:, the two together forming theblock. Held in suitable recesses formed in the adjoining faces of theupper and lower plates are the heads 13 of pins 12. The shanks of thesepins extend through suitable holes formed in the lower plate 14 and areso disposed that they lie at varying angles to the head block. Centrallydisposed on the head block and extending rearwardly therefrom is a bar18 provided at its rear end with a pin 18 which slants in the oppositedirection to the pins carried by the head block. Extending through asuitable opening in the head block and the bar 18 is a screw 17 having ahead upon its lower end and being provided on its upper end with a wingnut 19.

At 11 is indicated an adjusting plate which is slidably 'mounted on thepins 12 and through which passes the screw 17, the head of the screwfitting in a suitable recess Specification of Letters Patent.

on the under side of the adjusting plate. It will now be apparent thatby rotating the wing nut 19 in one direction the plate 11 will be raisedwhile if the wing nut be rotated in the other direction the plate willbe allowed to drop. In order to hold the plate depressed upon release bythe proper movement of the wing nut there are provided certain screws 16which extend through threaded openings in the head block plates and havetheir lower ends bearing against the upper surface of the adjustingplate 11. By means of these screws the adjusting plate 11 may beprevented from rising while if it is desired to permit the same to risethe screws 16 are unscrewed and the wing nut 19 rotated to lift theplate 11. This plate 11, as thus constructed, prevents too greatpenetration of the pins 12.

In order to provide proper means for drawing the head block along tostretch the carpet the head block has at each end an upstanding eye 16whereto are fastened the ends of a flexible strand such as a rope orwire 22. At 19 is a lever provided on its lower end with a spike point20 and having projecting from one side a hook 21. This hook 21 engagesin the bight of the strand 22 and by placing the spike 20 in suchposition that the handle of the lever 19 is slanted toward the headblock and then forcing this handle outward away from the head block theblock is drawn along. If, when this is done, the operator places hisknee upon the bar 18 the spike 18 will be forced into the flooring to asufficient degree to retain the carpet in position and the operator maythen proceed to tack the edge thereof in the usual manner.

There has thus been provided a simple and eflicient device of the kinddescribed and for the purpose specified.

Having thus described the invention, what is claimed as new, is

1. A carpet stretcher comprising a head block, an adjusting plate,carpet engaging pins connected with the head block and extending throughthe adjusting plate, and means for adjusting said adjusting plate withrespect to the head block.

2. A carpet stretcher comprising a head block having an upper plate anda lower plate, the latter provided with perforations, said upper andlower plates having opposed upper plate, and retaining means attached tosaid upper plate.

In testimony whereof, I afiix my signature, in presence of twoWitnesses.
